Launched in the year 2021, the 43HK6300 is a 43" 4K TV from Hitachi. It comes with a 10-bit IPS panel.
The maximum resolution it can achieve is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 103 ppi.
Picture Quality
After screen size and resolution, the next important spec of a display is its Color Reproduction (defined by its color gamut specification).
Hitachi has not provided a color gamut rating for this TV. But don't worry, we have other means to guess that.
Now, since the TV comes with a 10bit IPS panel, we can safely assume its equivalent sRGB coverage to be 100% or above. Undoubtedly The color quality on this TV will be Lifelike!
What Color Gamut means ?
Color gamut specification of a display is a measure of the range of colors that it can produce.
A panel with poor color reproduction will produce undersaturated/washed out colors that will not be pretty to look at.
Different manufacturers use different measurement standards to specify color gamut. Viz — sRGB (most popular), NTSC 1953, DCI P3 to name a few.
But don't worry, below is a chart that will help you choosing a TV with good color accuracy.
After color gamut, next in the list of important specifications that will impact your experience is Static Contrast.
Understanding the static contrast ratio of a TV
Static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (<1000:1) will not produce deep blacks. Apart from this, such TVs often suffer from backlight bleeds such as below:

This will affect your viewing experience, especially in a dark room.
Think of static contrast as another dimension to details — just like resolution. To put it into perspective, a TV with low contrast ratio will produce less shades of colors, so lesser detail overall.
This TV features a static contrast ratio of 8000:1., enough to produce deep blacks. The panel comes with local dimming technology which is a plus.
HDR10, HLG (Hybrid Log Gamma) and Dolby Vision are also supported on this TV.
As for brightness, it can go as bright as 350 nits. The backlight used on the panel is Direct LED.
Gaming Performance
If you are going to use your TV other than using it as a TV — say as a PC monitor or Gaming, you would want to take a TV with lowest input lag. For gaming, both the input lag and response time impacts the performance.
Sadly, Hitachi did not specify the input lag on this unit. Now, since this is not a cheap TV from Hitachi, we can expect an input lag of less than 20ms.
Understanding Input lag and response time
This lag is the latency at which your inputs changes the content of the screen. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
For best of both worlds, get a TV that has an input lag and response time of less than 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 43 inches and horizontally 37.95 inches. It is 3.23 inches thick. It weighs 5.34 kilograms and an additional 1.8 kgs if you include stand.
Coming to ergonomics — a VESA mount with interface size of 100 x 100 mm is provided for wall-mounting. The unit doesn't come with Swivel, Tilt or Pivot support.
Hardware and Audio
The core of this TV is powered by a 4-Core CPU. However, Hitachi didn't provide any information on the total RAM on the TV's specsheet.
For display connectivity, Hitachi has provided three HDMI 2.0 (ARC; CEC) ports on this TV.
To connect USB devices, you will have two USB 2.0 ports. Other connectivity ports include — 1x Satellite In (F-type female), 1x CI+, 1x Antenna (RF) and 1x Ethernet RJ45.
Wireless connectivity options on this TV include a 5Ghz Wi-Fi, 2.5 Ghz Wi-Fi, Wifi-Direct, Bluetooth and DLNA.
For audio, Hitachi has provided 2 x 10W speakers on the TV.
Speaking of power consumption, on average, this TV uses around 86.4 Watts and on standby, it uses 0.5 Watts.
For powering this unit, you will require an 220 V - 240 V/50 Hz outlet.
